I am successfully generating a file with this command using Cepstral:
But then from Asterisk v1.4 I get the following:
[Feb 3 21:04:18] WARNING[1233]: format_wav_gsm.c:142 check_header: Unexpected header size 16
[Feb 3 21:04:18] WARNING[1233]: file.c:311 fn_wrapper: Unable to open format wav49
[Feb 3 21:04:18] WARNING[1233]: format_wav_gsm.c:142 check_header: Unexpected header size 16
[Feb 3 21:04:18] WARNING[1233]: file.c:311 fn_wrapper: Unable to open format wav49
I have had this working in previous versions. Ideas?
